Question

3. Mechanical weathering :​

Answer 1

Answer:

Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.

Mechanical (or physical) weathering is the process by which physical forces break down rock, minerals and soil into finer particles. This article treats mechanical weathering as being separate from chemical weathering, even though both types of alteration occur concurrently in nature.
